Title
Body
file.contain.query.txt ENST001 ENST002 ENST003 file.to.search.in.txt ENST001 90 ENST002 80 ENST004 50 Because ENST003 has no entry in 2nd file and ENST004 has no entry in 1st file the expected output is: ENST001 90 ENST002 80 To grep multi query in a particular file we usually do the following: grep -f file.contain.query <file.to.search.in >output.file since I have like 10000 query and almost 100000 raw in file.to.search.in it takes very long time to finish (like 5 hours). Is there a fast alternative to grep -f ?
